That isn't a counter-argument, that's an analogy. It sounds quite nice, but it's also a bit a straw-man. The people who don't think technology is going to destroy work (I'm in that group) would never claim that there's a law of economics that says better technology makes more jobs. If you'll note in what I said, it's an observation about what people are (and what horses are not) that's going to keep things rolling. Namely that people are endlessly creative, and always wanting new things. That's kind of the point where the analogy with horses breaks down completely. Besides that of course, horses were valued for their muscles and not for their smarts. For as much as we as a community go on about AI, the robotics community hasn't even cost-effictively automated washing, drying, and folding laundry. To say that they're going to automate most knowledge work seems to me to be beyond grandiose. Not saying it's impossible, just not on any near-term timeline.
